The -5 (Dash Five) Part of the Hanford Z Plant by Dennis A. Armstrong

June 11 @ 7:00 PM - 9:00 PM

The Department of Energy Fact Sheet on this building called it one of “the most complex plutonium facilities” and “the most hazardous facilities on the Hanford Site.” For 40 years, starting in 1949, the Z Plant processed plutonium into “buttons” and plutonium oxide powder.

Dennis A. Armstrong will explore the naming of the -5 (Dash Five) Part of the Hanford Z Plant. He will delve into the 234-5 Building naming process and present a series of images detailing the Z Plant operations.

Dennis A. Armstrong has made significant engineering contributions at the Hanford Nuclear site to a broad spectrum of production and design activities including early defense weapons work, waste management and commercial reactor design. As vice president of a small company, he directed the design, production, and marketing of compacting presses for the manufacture of powder metallurgy parts and ceramic nuclear fuel. Before retirement, Mr. Armstrong led the Safety Related mechanical equipment operating license qualification program for the Columbia Generating Station 1,100-megawatt commercial nuclear power plant. His strong reputation for engineering knowledge and integrity led to his selection as “Engineer of the Year” by the Columbia Basin Section of ASME in 1985. He has supported ASME at many levels, including vice president, Public Information, and vice president, Region VIII, plus active involvement in numerous committees and the local Columbia Basin Section. ASME Life Fellow, BSME, Washington State University.
